NASA looks to solar eclipse to help understand Earth’s energy system

20 July 2017

It was midafternoon, but it was dark in an area in Boulder, Colorado on 03 Aug, 1998. A thick cloud appeared overhead and dimmed the land below for more than 30 minutes. Well-calibrated radiometers showed that there were very low levels of light reaching the ground, sufficiently low that researchers decided to simulate this interesting event with computer models. Now in 2017, inspired by the event in Boulder, NASA scientists will explore the moon's eclipse of the sun to learn more about Earth's energy system.
